Question

我想创建一个64位ASP.NET MVC 2 Web应用程序，并使用64位类库引用它。但这样做我得到一个“System.BadImageFormatException”-Exception

我添加的每个项目/解决方案都是.Net 4.0：

我创建了一个名为“MySolution”的新空白解决方案
我向该解决方案添加了一个新项目（ASP.NET MVC 2 Web应用程序），名为“MyMvcApplication”，没有测试单元使其更容易（Visual Studio要求创建一个）

到目前为止，“MyMvcApplication”正在运行。即使将其设置为x64。

我在soltion（类库）中添加了一个名为“MyClassLibrary”的新项目
我将“MyMvcApplication”设置为启动项目（它应该已经存在，但只是为了完整列表我所做的事情）。
我转到菜单Build / Configuration Manager，通过从“Any CPU”复制创建一个新的平台“x64”。然后我将两个项目都设置为x64。
现在我有Debug | x64和“MyClassLibrary”和“MyMvcApplication”平台到x64和“构建框”勾选。
我将“MyMvcApplication”中的引用添加到“MyClassLibrary”（添加引用，进入“项目”选项卡并选择“MyClassLibrary”）。

我运行“MyMvcApplication”并收到以下错误：

Could not load file or assembly 'MyClassLibrary' or one of its dependencies.
An attempt was made to load a program with an incorrect format. 
Description: An unhandled exception occurred during the execution of the

Assembly Load Trace: The following information can be helpful to determine why the assembly 'MyClassLibrary' could not be loaded.

=== Pre-bind state information ===
LOG: User = Dev\Chris
LOG: DisplayName = MyClassLibrary
 (Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: MyClassLibrary | Domain ID: 2
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.

编辑：

运行“corflags c：\ Test \ MySolution \ MyMvcApplication \ bin \ MyClassLibrary.DLL”，就像在visual studio命令提示符中的bobbymcr建议我得到：

Version   : v4.0.30319
CLR Header: 2.5
PE        : PE32+
CorFlags  : 1
ILONLY    : 1
32BIT     : 0
Signed    : 0

但我不知道如何处理这些信息： - （

EDIT2：

将所有项目切换到x86并运行ASP.NET MVC 2 Web应用程序时，出现以下错误：

Parser Error 
Description: An error occurred during the parsing of a resource required to service this
request. Please review the following specific parse error details and modify your
source file appropriately. 

Parser Error Message: Could not load type 'MyMvcApplication.MvcApplication'.

Source Error: 

Line 1:  <%@ Application Codebehind="Global.asax.cs"
Inherits="MyMvcApplication.MvcApplication" Language="C#" %>


Source File: /global.asax    Line: 1

所以无论是否切换到x86或x64，我都会收到错误。

我该怎么办？

Answer 1

事实是x64位应用程序可以加载x86和x64程序集。但是x86应用程序只能加载x86程序集。 Casini（Visual Studio Development Server）是x86应用程序，这就是它不支持运行x64 Web应用程序的原因。您必须仅在支持x86和x64的IIS上托管x64 Web应用程序。

还要确保您的类库的Target平台是“.NET Framework 4.0”，而不是“.Net 4.0 Client profile”。
